Abstract (en)
A proposal is made of an image display device capable of reducing power consumption with improved effectiveness even when a sync signal sensor fails to sense both of horizontal and vertical sync signals. When a first sync signal sensor fails to sense both of horizontal and vertical sync signals, a main power source, a heater power source device, and a first sync signal sensor power source device are turned off. Power is thus saved. When a second sync signal sensor senses at least one of the horizontal and vertical sync signals, the first sync signal sensor power source device that is turned off is turned on. <IMAGE>
